Scotland’s Drinking Water has never been better

Favourable Water Quality Report

The Drinking Water Quality Regulator’s annual report on Scotland’s tap water shows that the quality of what we are drinking is the best ever. The report by the DWQR on the quality of supplies during 2010 found that well over 99% of tests on samples complied with strict regulatory standards.

Water Quality Tests

In 2010 Scottish Water carried out nearly 324,000 tests on its water at treatment works, storage reservoirs and consumers’ taps. Of the 155,302 tests on samples taken directly from taps in people’s homes, 99.83% met the standard. This compares with 99.78% in 2009 and 99.14% in 2003, the year after Scottish Water was formed. Compliance for most parameters showed an improvement, significantly so for pH (hydrogen ion), colour, iron and Trihalomethanes (THMs). The number of failures for this last parameter attracted criticism from the Regulator for the high failure rate, so this year’s figures are to be welcomed although more still needs to be done in some areas.

Happy Customers
Consumer satisfaction with the water supply across Scotland is up too. In 2010 Scottish Water received 20,495 contacts from consumers concerned about the quality of their supplies, compared with 24,168 in the previous year, but the DWQR would like to see these numbers fall further:
A DWQR spokesman said:
“We are delighted with these results that show that Scottish tap water is top quality. The people of Scotland can draw a glass of water from the tap and be confident that their supplies are tested thousands of times each year and that they meet some of the tightest quality standards in the world.  It’s very important that the water tastes and looks good too and it’s comforting to see the number of complaints to Scottish Water reduce. DWQR believes that this figure has further to fall and the work Scottish Water is doing to renovate old iron water mains and improve its control of chlorine at treatment works should achieve this.”
Not everyone in Scotland receives their drinking water from Scottish Water – some 150,000 people, approximately 3% of the population, receive water from a private water supply. The quality of some of these supplies remains of concern, and 18.35% of samples taken from these supplies last year by local authorities contained the E.coli bacterium.

The DWQR spokesman said:
“Local Authorities across Scotland are working hard to communicate the health risk these private supplies pose to the owners and users and offering support to make improvements. Where improvements are being made it is vital that the new treatment that is installed is properly maintained so that the benefit is not lost.”
